StockholmNynäs

StockholmNynäs is a former Swedish railway company that operated on the Nynäs Line, a commuter rail line south of Stockholm. The company was established in 2000 as a subsidiary of the Stockholm Transport Authority (SL) and was responsible for operating and maintaining the Nynäs Line. This line connects the city of Stockholm with the peninsula of Södertörn, serving several municipalities including Nynäshamn.

The primary function of StockholmNynäs was to provide public transportation services for the growing population in the southern suburbs of Stockholm. The company managed train operations, including scheduling, staffing, and ensuring the smooth running of services. They were also involved in the upkeep of the railway infrastructure and rolling stock used on the Nynäs Line.

In 2009, SL decided to integrate the operations of StockholmNynäs into its own organization. This move was aimed at streamlining public transport management within the Stockholm County and achieving greater operational efficiencies. Following this integration, the StockholmNynäs company ceased to exist as an independent entity, and its responsibilities were absorbed by SL. The Nynäs Line continues to be a vital part of Stockholm's commuter rail network, operated directly by SL.
